Question

excretory organs in earthworm and insects?

only for bunny ​

Answer 1

Answer:

The excretory organs occur as segmentally arranged coiled tubules called nephridia. They are of three types septal nephridia, integumentary nephridia, and pharyngeal nephridia. A nephridium starts out as a funnel that collects excess fluid from the ceolomic chamber. The funnel connects with a tubular part of the nephridium which delivers the wastes through a pore to the surface in the body wall into the digestive tube.
